Privacy Policy
The short version: your journal is yours. Entries are written for your eyes, stored on your device first, never sold, never used for advertising, and never read by us. You can export or delete everything, on any tier, at any time.
1. What this covers
This policy describes how Sharp Thought ("we", "us") handles your information when you use the Sharp Thought apps and website. It covers the web app, the mobile apps, and this site.
2. What we collect
- Account data. Email address, display name, and password (stored as a salted hash by our authentication service). Used to sign you in and to send account emails such as verification and password reset.
- Journal content. Your entries and notes are stored on your device first. When sync is enabled, content is stored on our servers with end-to-end encryption as that capability rolls out; where encryption applies, we hold ciphertext we cannot read.
- Profile image. If you upload an avatar, it is stored under your account in our media storage and shown only to you.
- Settings. Preferences such as reminder time and display options, synced so your setup follows you across devices.
- Usage metadata. Coarse, content-free signals: the days on which your account made requests, and anonymous per-quote counts (for the "N wrote on this" feature). Never the text you write, never your route through the app.
- Optional context. If you enable "Sense place & weather", your approximate location is used on-device to tag entries. It is part of your journal content and treated the same way.
3. What we do not do
- We do not sell or rent your data — to anyone, ever.
- We do not show ads and do not share data with advertisers.
- We do not read your journal, and we never log entry text or personal details to analytics or crash reporting.
- We do not train AI models on your journal.
4. AI features
AI features (such as refining an entry or periodic reflections) are optional and individually switchable, and a full "No AI" mode exists. When you use one, the relevant text is processed transiently to produce the result and is not retained after the request completes. AI features never provide medical advice or diagnosis.
5. Where your data lives
Journal content lives in your device's local storage first (the app works offline). Synced data is stored on Cloudflare infrastructure (database, media storage) under your account identifier. Authentication is handled by our own account service; sign-in tokens are kept in memory and platform secure storage.
6. Your rights and controls
- Export. One-tap full export of your entries is always available, on every tier.
- Deletion. You can delete entries and notes at any time. To delete your account and all server-side data, contact us at the address below.
- Access & correction. Ask us and we will show you what account data we hold and correct anything inaccurate.
7. Cookies and local storage
The apps use browser local storage for your session token and cached profile so you stay signed in, and a local database for your journal. No third-party tracking cookies are used.
8. Children
Sharp Thought is not directed at children under 13 (or the equivalent minimum age in your jurisdiction), and we do not knowingly collect their data.
9. Changes
If this policy changes materially, we will note the new effective date here and inform you in the app before the change takes effect.
